Thanks...I ended up leaving them at a local place in Coventry (Wheels UK) to get what looks like a similar satin matt black finish to KadeSdad. Costing £60 a wheel to correct some minor curb rash and powder coat the wheels.
Spent quite a long time there looking around and watched him powdercoat a set of wheel, seems like he knows what he is doing although the place could do with a bit of a tidy up...fingers crossed he makes a decent job of it.
